THRE AD-GUIDE FOR SPOOLlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 230,509, dated July 27,1880.

Application filed April 3, 1880. (ModeL) To all whom it may concern Beit known that I, CHARLES Gr. TRAFTON, of Slatersville, in the county ofProvidence and State of Rhode Island, have invented a new and ImprovedThread Guide for Spooling- Machines, of which the following is aspecification.

The object of my invention is to furnish a thread-guide that shall beself-adjusting to the yarn as the latter runs from the bobbin to thelarger spool, so as to avoid friction.

The invention consists in a guide-plate provided at one end with acurved friction-surface and at the other with a slotted flange and aplate, in combination with arod having projections at its top to limitthe movements of said plate sidewise and a screw which serves as a pivotfor said plate. as hereinafter described and claimed.

In the accompanying drawings, Figure l is a sectional side elevation ofmy improved thread-guide. Fig. 2 is a perspective top view of the same.Fig. 3 is a cross-section of the swinging guide-piece on line y y ofFig. 2, and Fig. 4 is a plan view.

Similar letters of reference indicate corresponding parts.

The guide consists of the supporting-rod A, fitted for being screwedinto the rail of the spoofing-machine, and the swinging guidepiece B,that is attached upon the flanged head of rod Aby a screw, a, so that itmay swing on the screw in ahorizontal plane, such movement being limitedby projections b on the head of rod A.

The guide-piece B is preferably made of sheet-steel stamped to shape,and is formed at one end with the curved portion a, which is thefriction-surface over which the yarn runs. At the opposite endthe endfarthest from pivot -a-the piece B is formed with a vertical flange, d,that is slotted for the yarn to pass through.

Upon one side of flange d a plate, 6, is attached, and this plate isformed with an angle portion that extends through the yarn-slot. Theplate 6 is attached by a screw or rivet passing through a slot in 0, sothat theiplate may be moved to close the yarn-slot morepr less,according to the size of the yarn. The plate 6 may, however, bedispensed with when no adjustment is needed, and the friction-surface 0may consist of a tube attached to the piece B.

In use the yarn from the bobbin passes over the surface 0 and throughthe slot of the flange d to the spool on which it is to be wound. Theguide piece B, being light and easily moved on its pivot, is moved bythe yarn, so that the latter may pass in a straight line from the bobbinto the spool. This movement becomes greater and more essential as thespool increases in size, and the guide is self-adjusting, as required.By this swinging movement the draft on the yarn is equal at all times asit passes freely through the slot, and there is no tendency to wear agroove at the side of the slot. The guides are thus rendered durable,and do not become useless by wear after a short time, as is the casewith fixed guides.

I am aware that it is not new to secure a slotted guide-plate to an armpivoted to its support, or to provide a sliding slotted plate with arms,one of which is adjustably secured in a slotted head, or to provide aslotted guideplate with an adjustable plate for increasing ordiminishing the width of said slot.

The advantages of my device over these are as follows: The guide restsupona smooth surface, and as the spool fills the thread crosses thefriction-surface at different angles, preventing wear, and the plate 6has a rightangled bend that projects through the slot of flange d, so asto greatly increase the bearingsurface for the thread.

What I claim as new and of my invention The combination of the plate B,provided at one end with the curved friction-surface c and at the otherwith the slotted flange d, and the plate 6, with the rod A, havingprojections 12 and screw to, substantially as and for the purposedescribed.

CHARLES Gr. TRAFTON.
